Abstract

Copper substrates were functionalized using ultrashort pulsed laser surface processing to create micro- and nano-scale features to enhance the electrocatalytic nature of the surfaces for the electrochemical reduction of carbon dioxide. Post-processing of the laser-functionalized copper surfaces was carried out to increase the efficiency and stability of the electrocatalyst. A maximum current density of 55 mA/cm² was achieved during carbon dioxide reduction reaction (CO2RR) over the laser processed copper, and the stability of the surface was enhanced by modifying the chemical and physical nature of the surfaces. The surfaces were chemically and physically analyzed before and after the reduction reaction.
